Abstract
A volumetric solid and liquid dispenser includes a drum sized for receiving and containing a predetermined volume of solid material from a solid material supply source. The supply source can be a hopper positioned above the drum. The drum is rotatably mounted to a support frame and can be rotated from a position in which it receives solid material from the supply source to a dispensing position in which it dispenses the solid material into a receptacle below. A liquid metering and dispensing container dispenses a predetermined volume of liquid into the receptacle for mixing with the solid material. The invention is particularly useful for dispensing predetermined volumes of sand and water into a cement mixer for mixing with mortar.
Claims29
A portable apparatus for dispensing a solid material and a liquid material into a mixer, comprising:
- (a) a drum having an opening therein and sized for receiving and containing a predetermined volume of solid material from a hopper positioned above said drum for allowing free flow of the solid material into the drum;
- (b) a discharge assembly for discharging the predetermined volume of solid material from said drum into the mixer;
- (c) a container for dispensing a predetermined volume of liquid into the mixer for mixing with the solid material;
- and
- (d) a support frame for mounting said drum, said hopper and said container in an elevated position above the mixer.
A method for dispensing a predetermined volume of solid material and a predetermined volume of liquid material into a mixer, comprising the steps of:
- (a) providing a dispensing apparatus comprising:
- (i) a drum having an opening therein and sized for receiving and containing a predetermined volume of solid material from a hopper positioned above said drum for allowing free flow of the solid material into the drum;
- (ii) a drive apparatus for moving said drum from a receiving position wherein the opening in said drum is positioned to receive the solid material from the hopper, and a dispensing position wherein the opening in said drum is positioned to dispense the sand to a mixer positioned below the drum,
- (iii) a container for dispensing a predetermined volume of liquid into the mixer for mixing with the solid material, and
- (iv) a support frame for mounting said drum, said hopper and said container in an elevated position above the mixer;
- (b) positioning the drum in the receiving position to allow for free flow of the solid material from the hopper into the drum until the drum is full;
- (c) filling the container with the predetermined volume of liquid;
- (d) dispensing the liquid into the mixer;
- and
- (e) rotating the drum to the dispensing position to allow the solid material in the drum to flow through the drum opening and enter the mixer.
A method for making a predetermined amount of cement comprising the steps of:
- (a) providing a dispensing apparatus comprising:
- (i) a drum having an opening therein and sized for receiving and containing a predetermined volume of sand from a hopper positioned above said drum for allowing free flow of the sand into the drum,
- (ii) a drive apparatus for moving said drum from a receiving position wherein the opening in said drum is positioned to receive the sand from the hopper, and a dispensing position wherein the opening in said drum is positioned to dispense the sand to a mixer positioned below the drum,
- (iii) a container for dispensing a predetermined volume of water into the mixer for mixing with the sand, and
- (iv) a support frame for mounting said drum, said hopper and said container in an elevated position above the cement mixer;
- (b) positioning the drum in the receiving position to fill the drum with sand from the hopper;
- (c) filling the container with the predetermined volume of water;
- (d) dispensing the water into the mixer;
- (e) rotating the drum to the dispensing position to allow the sand in the drum to flow through the drum opening and enter the cement mixer;
- (f) adding a predetermined volume of mortar mix to the cement mixer;
- and
- (g) mixing the sand, water and mortar mix together to form cement.
